Description:

BACKGROUND

1. Field of Invention

This invention relates to multi-position reclining beds including new reclining features and attachable desk.

2. Description of Prior Art

Reclining beds were originally used in hospitals to allow patients to sit up in bed, allowing care takers to crank up the back section of the bed rather than arrange pillows and position the patient towards the head board of the bed and thenhaving to lay them flat again. The reclining bed then allowed the patient, through a powered crank or motorized actuator, to change the incline of the back section of the bed. The reclining bed eventually became available for the general public, havingthe same powered back reclining feature as well as the elevated feet, calve and thigh section to raise above the flat rest position. Since this reclining bed dramatically improved the conventional single position flat bed, user satisfaction wasimmediately realized. The improvement was significant enough that public demand for more comfort was alleviated nor was further comfort conceived possible from a bed. The reclining bed added the wall hugging feature as seen in Elliott, to allow the endtable to stay within reach of the user by moving the back section headward as it was reclined upward. (other sections also moved headward with back section)

The reclining chair with a blanket offered a warm sit-up furniture for watching television or reading and generally placed beside an end table, for drinks and under a lamp. The reclining chair evolved to further allow the user to bring thechair to a flat coplanar position, as seen in Kerstholt, however, such chairs comprised of three sections, back, thigh/buttocks and calve, and offered feet elevation without a horizontal calves section, resulting in the feet being pushed upward andshifting leg weight onto the knees. Kerstholt neither has a boxspring or mattress to tuck or sandwich sheets and blankets into such as a reclining chair, and should be classified as a chair for sleeping, not a wallhugger bed. The point at which a chairbecomes a bed may be determined by the following: a) if sheets, blanket and mattress are a permanent part of the furniture. b) the size of surface being wide and long enough to facilitate sheets blankets. A standard adult mattress is 36 inches wide by80 inches long. c) sheets and blankets would tuck in-between a boxspring and mattress rather than draped over a chair. d) the width being sufficient to allow a sleeping person to roll from one side to their back to their other side. If this is not thecase the furniture should be classified as a cot, lawn chair, or reclining chair. e) the length being sufficient to facilitate a pillow clearance above the head, and clearance at foot end to allow the feet of the person to not only rest on the mattressbut sufficiently inward to allow blankets to remain sloped. f) the mattress is independent from the surface. g) the compressibility of the mattress or independent cushion suitable for sleeping rather than sitting.

The reclining bed has the long felt but unrealized disadvantage of ergonomic discomfort in that the body weight of the thighs was slightly shifted towards the buttocks and lower back area due to thighs and feet being raised beyond horizontal andinclined towards and thus bearing on the buttocks and lower back. At the same time the buttocks and lower back are also carrying the weight of the head, shoulders and back that would be transferred to the lower thighs (just above the knee area of thethighs) when sitting up fully in a chair, especially when leaning forward. This is readily felt when reclining in a typical lawn chair where the buttocks section is horizontal, especially when the calve section is also horizontal and no padding ispresent, even though the bodyweight of the back, head and shoulders is partially supported by the inclined back section. Three section chairs such as Kerstholt recognize the importance of the buttocks section being tilted. This ergonomic problem isalso present with the present reclining beds but is masked or retarded by the effect of the mattress softness and the illusion that the body weight is transferred to the lower thighs since the mattress does touch this area. However with back reclinedand more so with feet elevated simultaneously (fetal position), long periods in this position results in discomfort in the lower back and tailbone or buttocks due to this absence of weight transfer to the lower thighs. The fetal position also results indiscomfort due to the diaphragm being squeezed by the additional weight not being transferred to the lower thigh area, even though it appears to be similar to the full sit up position, the body is generally horizontal and not vertical. There very fewsituations where the human body is held in the horizontal fetal position in the natural world unless suspended in liquid or floating, when there is virtually no body weight.

The applicant's invention solves this problem with a bed that will move into a full sit up position and body weight transfer to the lower thigh area as well as feet. This development makes long term sitting up in bed possible and thus makesworking and recreation of the full sit up position comfortable, hence making a desk, office and recreational device as part of the bed a necessity. The applicant also solves the problem of a standard reclining chair cannot be used with a standard officedesk since it is difficult to slide into the location close enough to the desk and still allow entry and exit. The feet and arm rests would also hit the desk rear and drawers. People who work long hours behind the desk will benefit from the variationthe reclining bed offers over the most comfortable office chair. Tables for beds exist basically for the purpose of eating during illness, rather than bed trays, and are detached from the bed for the practical reason for use of the same table for otherpatients, removal when not in use, adjustment for various reclined positions as well as body thickness and back pillow thickness. The eating period is usually short and reading or television require no table surface. The bed may also be required to berushed into an emergency room and an attached desk would interfere with transport and accessibility. Home use does not require the dettachability of the desk, but this has not been realized and hence invented as part of the bed. The ergonomic timelimitation before discomfort is felt has also prevented the need for a desk to be realized or identified. The reclining bed is recreationally used for reading or television. The use for writing or lap top computer work is not commonly realized, desiredor practiced since: a) writing and computer work is not expected or possible for people in the hospital. b) computers require electrical and phone jacks for internet connection and possibly desk space for supporting paper work, diskette availability,etc., making it simpler to just get up and go to the desk since the user has to get up any way to get the computer. The recent availability of lap tops has made the bed office viable as files, phone numbers and other various written information do nothave to be retrieved from filing cabinets or require desk space. Full size computers would be too awkward to move to a separate office location in the home. c) internet connection of lap tops require accessible phone jacks in the bedroom which is themain reason that is not commonly realized and practiced d) tables used in hospitals are not common in bedrooms unless person is ill, and for non ill people a tray with support stands for "breakfast in bed" is sufficient. e) the wall hugger reclining bedprovides access to side tables generally located at head of bed to allow enter and exit of bed, for alarm clock, drink, or book. f) beds are perceived to be used for activities prior to sleep g) sitting up with legs straight out is intuitively realizedto be uncomfortable for long periods h) an attachable desk on a bed that reclines and especially one that moves toward the wall while reclining is not conceivable, even for someone skilled in the art, to attach a desk and especially one with electricalwiring, for fear of crushing against the desk will reclining or electrical shorts to dangling wires. J) hoisting devices are located along the head end of the bed for accessibility by hospital staff and for enter and exit accessibility.

The mattress has generally been placed on a boxspring, having legs for foot clearance and a covered with fabric to allow sheets and blankets to be smoothly slid sandwiched between them. It's primary function is to provide a rigid or semi rigidflat surface elevated from ground to allow feet to project under the bed when "making the bed". Most boxspring surfaces are no longer flexible but are usually made of a low cost chip board or thick cardboard. The conventional consumer perception of aboxspring similar in thickness to the mattress has prevented beds with single plywood sheet and long legs to be successful in the market place even with the reduction in material, delivery and storage cost benefit. This paradigm has made the recliningbed with leg sections dropping below horizontal inconceivable as well as impractical due to the short distance it may be able to drop rendering little gain for the added expense of such a feature. It would also be impractical to increase the overallheight of the boxspring to allow for the necessary leg drop clearance since the overall height for sitting when the bed is flat would be high and uncomfortable not to have feet touching the ground. The reclining bed has several design problems thatwould make this feature of the leg section dropping below the horizontal position very difficult; a) pivot point between the buttocks section and the thigh section requires a pivot point at the same elevation but under the knee area for the bottom pivotof the double bar linkage to elevate the calves section horizontally as it is recline in an upward or downward direction. This pivot point is named the "lower feet lifting bar pivot 23" of the "feet lifting bar 21" in FIG. 3. This pivot point must besecured to the frame or carriage and would prevent the leg sections from dropping below the horizontal position. If the pivot points were located outside of the drop area say on side boards, then the side boards would prevent two beds from sitting sideby side with mattresses touching and the side boards would have to move along the floor to hug the wall as the back section reclines upward and a device to lock the calves section and thigh section coplanar would also have to be added. b) the linearactuator needs to be centrally located width wise and since the back section reclining actuator is located centrally at the head of the bed, the feet elevating linear actuator has generally been placed below the calves section, thus preventing droppingof the leg section. The other main reason for the location of the linear actuator was that to prevent crushing to children during return to the horizontal position, the linear actuator is not connected to the feet elevating linkage for pulling but onlyfor pushing, allowing return by free fall of the leg section to horizontal. As well the space limitation due to actuator size and symmetry and duplication of components, the actuator is located below the calves section. C) since the wall hugger isdominating the market, over the non wallhugger, it became even more inconceivable that the leg section now moved further towards the head of the bed can be made to drop, since it would also have to drop through the carriage and carriage track andpedestal or track support structure as well as the pivot point.

SUMMARY

In accordance with the present invention, a reclining bed that provides the full ergonomic benefits of sitting up with the additional benefits of back arch support, foot rest, arm rest and blankets, all positions adjustable to allow shifting ofweight makes this bed a more comfortable work place than any known desk and chair available and warrants the special desk to take advantage of long sitting periods now possible in this bed. This bed offers independence and many benefits to handicappedor seriously injured people.

DESCRIPTION--PREFERRED EMBODIMENT

FIG. 1--A preferred embodiment of the present invention of the reclining bed with desk shows the main features of the bed in terms of it's ergonomic advantages that transform the reclining wall hugger be into long term sit-up position equivalentto and exceeding the ergonomic attributes of a comfortable chair, further warranting a desk for long periods of work or recreation.

FIG. 2--Shows the bed sections in the horizontal and sit-up position with the mattress 8 showing the sit up position only and the carriage 5 and carriage wheels 6 with heavier lines in the sit up sit-up location along the track 7 held by frame9. The numbered sections of the bed are in the sit-up position, and unnumbered sections are in the horizontal position. The back section 1 is pushed up by back bar 24 as the bed moves in the head ward direction as it rotates about the pivot pointbetween the back section 1 and buttocks section 2 while the buttocks section 2 and carriage 5 is rolled along track 7 supported by the frame 9 and it's legs.

FIG. 3--Shows the bed calves section and thigh section mechanism in the feet elevated position including pivot fixture 10, transfer link 11, projection 12 and stop 13, connecting bar 14. Transfer link 11 has three pivot points, lower pivot 16is connected to the linear actuator 17, the foot end pivot 18 is pivotably connected to the connecting bar 19 and the opposite end of the connecting bar is pivotably connected to said feet elevating mechanism 20. The feet elevating mechanism 20 iscomposed of the thigh section 3, calves section 4 and feet lifting bar 21. The transfer link fixture pivot 22 is pivotably connected to the pivot fixture 10, the pivot fixture 10 is pivotably connected at the axial pivot location between the buttockssection 2 and thigh section 3. The location of the lower feet lifting bar pivot 23 which is connected to the pivot fixture 10 is the essential location that permits the configuration of the double bar linkage of the feet elevating mechanism 20 to haveapproximately equal length and parallel spacing of the thigh section 3 and the feet elevating bar 21 (double bars), in order to allow the calves section to remain horizontal during elevation. The lower feet lifting bar pivot 23 would normally be fixedand prevent downward rotation of the thigh section 3, but since this pivot point is moved out of the way by the pivot fixture 10 when the feet are no longer elevated, dropping of the thigh section 3 below horizontal is thus made possible.

While thigh section 3 and calves section 4 are inclined below horizontal, the force of footward motion of the thigh calve and knee linear actuator 17A on the lower pivot point 16 of transfer link 111 results in upward rotation of the pivotfixture 10, calves section 4, thigh section 3, and feet elevating mechanism 20 in an upward direction about the distal end pivot of pivot fixture 10 until the projection 12 of the pivot fixture 10 engages stop 13 secured to thigh section 3 at asubstantially horizontal position. Further footward motion of the thigh calve and knee linear actuator 17A results in rotation of the transfer link 11 about the transfer link fixture pivot 22 resulting in lifting of the thigh section 3 and calvessection 4 and feet elevating mechanism 20 from resting points on pivot fixture 10 and calves section stop 13. The pivot fixture is preferably constructed of structural steel angle iron with protrusion 12 being part of the angle iron.

FIG. 4--Shows two lock spring 15 in their fully elongated state which prevent the feet elevating mechanism 20 from collapsing onto the pivot fixture 10 if there is a downward force on the calves section 4, and also keeps the pivot fixture 10horizontal. The two spring 15 also force the transfer link 11 to remain in an over center locked position when feet elevating mechanism 20 is horizontal as well as below horizontal, thus locking the thigh section 3 and calves section 4 and pivot fixture10 into a single rigid coplanar unit.

FIG. 5--Shows the two lock spring 15 in less elongated or collapsed position but still partially elongated to maintain an over center locked position when feet elevating mechanism 20 is horizontal as well as below horizontal, thus locking thethigh section 3 and calves section 4 and pivot fixture 10 into a single rigid coplanar unit.

FIG. 6--Shows the locked thigh section 3 and calves section 4 and pivot fixture 10 into a single rigid coplanar unit in the sit-up position.

FIG. 7--Shows the disposed locations of the pivots and double bar linkage lengths to form a configuration that will result in substantially minor vertical movement of the foot edge of the calves section 4 of the coplanar configuration of thighsection 3 and calves section 4 when buttocks section 2 is reclined. The lower transfer link pivot 16 is disposed along pivot fixture 10 so that the thigh calve and knee linear actuator 17A (for the thigh section 3 and calves section 4 which remainsinactivated) and buttocks section 2 form a double bar linkage resulting headward and footward movement of the foot edge of the calves section 4 during the buttocks section 2 section respectively raising and lowering in inclination with substantially novertical movement of the foot edge of the calves section 4.

FIG. 8--Shows the buttocks section 2 reclining mechanism with the collapsing boxspring cams. The peripheral frame 25, pivoted at it's distal end pivots, forms the lower edge of the foot end of the bed, and along both sides of the bed at adistance of about 10 inches below the surface of the calves section 4 and/or thigh section 3, covered by fabric (not shown) to give the appearance of a boxspring, to provide a protective elongatable fabric type shroud which encloses the moving parts, andprevent the peripheral frame 25 from resting on bed covers, blankets, sheets and/or floor during horizontal travel. The cam contour controls the elevation position of the peripheral frame 25 when the thigh section 3 and calves section 4 are reclinedbelow the horizontal position and relies on the tensile force of the fabric along the foot edge of the calves section 4 when reclined above the horizontal (feet up position). The buttocks section 2 can be tilted at any position along track 7 as thebuttocks section linear actuator 17B for the buttocks section 2 reclining, lower cam arm 27, upper cam arm 26 move with carriage 5. The cam follower 28 rests on the cam portion of the lower cam arm 27 during buttocks section 2 reclining. The lower camarm 27 is secured to lower cam arm 27 of the opposite side by the cam arm crossbar 29 which is pivoted about carriage 5 when the buttocks section linear actuator 17B is retracted, resulting in an upward movement of the buttocks section 2 by means of thetransfer to the two upper cam arm 26 through the common pivot with the two lower cam arm 27.

FIG. 9--shows the bed with the buttocks section 2 horizontal and calves section 4 and thigh section 3 below horizontal. The cam follower 28 is supported by the cam portion of the upper cam arm 26.

FIG. 10--shows the bed with the buttocks section 2, calves section 4, and thigh section 3 horizontal. The cam follower 28 is not touching neither lower cam arm 27 or upper cam arm 26. The peripheral frame 25 is supported by the tensile forceof the fabric along the foot edge of the calves section 4.

FIG. 11--shows the fabric covering of the boxspring, and the bed with the buttocks section 2 horizontal, calves section 4, and thigh section 3 in the feet up position. The cam follower 28 is not touching neither lower cam arm 27 or upper camarm 26 (not shown). The peripheral frame 25 is supported by the tensile force of the fabric along the foot edge of the calves section 4. Side fabric covering 30 is typically heavier density non stretchable fabric requiring expansion pleats 31 that foldinward when bed is horizontal so that it is not visible. The underside fabric 32 is lighter, stretchable fabric to provide safety and is partially along peripheral frame 25 to allow stretching over frame 9 when thigh section 3 and calves section 4dropped below horizontal.

FIG. 12--shows the side fabric 30 collapsed when the bed is in the sit-up position with the pleats 31 hidden from view. The underside fabric 32 requires minor stretching over frame 9.

FIG. 13--shows the carriage linear actuator mechanism, for back section 1 reclining, connected between the carriage 5 and the frame 9 (See FIG. 14 for details). The threaded rod 33 is rotated by linear actuator drive motor 40. During reclinefrom horizontal to sit-up position of back section 1, the carriage is pushed in the headward direction by the rotating thread 33 forcing the nut 35 into the socket 34 which is secured to the carriage 5. This movement requires significantly higher forcethan the reclining downward to horizontal since there is the weight of body and back section to elevate. During the recline downward to horizontal, the carriage is pushed in the footward direction by the rotating thread 33 forcing the nut 35 into thethrust ball bearing 36 which pushes against compression spring 37, which pushes against the bushing 39 which pushes against the bearing housing that is secured to the carriage 5. If the back section motion becomes blocked by a body part or blankets, thenut 35 will advance along threaded rod 33 as footward carriage movement is halted resulting in the compression of compression spring 37 until the nut 35 is completely out and disengaged from the socket 34. At this point the threaded rod and nut rotatefreely against thrust ball bearing and crushing force is limited to the compression force of the compression spring 37 and the resulting frictional forces between the threaded rod 33, nut 35, and thrust ball bearing 36. After the blockage is removed,the weight of body and back section will move the carriage footward until the nut 35 rests against the socket. Rotation of the threaded rod 33 will then result in the nut 35 seating itself in the socket 34 causing only a minor backward falling motion ofthe back section 1.

The high frictional surface 41 results in headward direction of slipping of mattress 8 on relatively low friction surface of back section 1, during reclining from horizontal, and forming of mattress to back section 1 and thigh section 2 (ratherthan the lifting of the mattress 8 from surface), and displacement of mattress 8 past head edge of back section.

FIG. 15--shows a side view of the bed with the desk assembly, foot rest assembly and buttocks sling.

The desk top 42 has tilt and height adjustments and extension section to increase versatility of use such as for lap top computer, book holder, writing surface, eating surface, etc. The desk cabinet 43 holds electrical and phone outlets, lamps,alarm clock, storage area for various objects, etc. The arm rests 44 adjusts for width and tilt and fold inward when used as side table or end table. The buttocks sling 50 and back sling 51 are connected to the armrests 44 and may disconnected forsleeping or not in use or if desk is to be swung out of way. The desk assembly height is adjusted by the height adjustment actuator 52 which may be a powered actuator, hand crank or lock pin to lift or lower the column 45 in column base 46. The columnbase 45 does not rotate within the column base 46. The swivel lock 47 (three shown) has electrically activated lock release and locking device for a rotated column to allow various position locking. The swivel lock 47 would be operated by variousswitches simultaneously or independently from various locations such as the armrest 44 or desk cabinet 43. The lock and release action of the desk assembly will allow incremental support and hoisting for enter and exit of bed. A person suffering injuryor weakness may connect buttocks sling 50 and back sling and then lower buttocks section 2, insert bed pan, or use hands and or feet on mattress to swing themselves over to edge of bed, wheel chair, toilet device, or walking aid. The buttocks sectioncan be raised when sitting over bed edge to release buttocks sling 50 and back sling 51.

FIG. 28A--A sensible shape identification control switch for a reclining bed where the control is permanently mounted or hand held, whether the control housing or switch arm 92 has the protrusion 91 represents the pillow or head of a person tosensibly identify the switch for the back section and at the same time identify the orientation of the switch, which in turn identifies the calve/thigh section as not having the head, and in the case of this bed, the buttocks section in the middle. Theswitch arm 92 is pivoted at the pivot point 93 to which the rotation on the switch arm 92 would correspond to the movement of the back section or calves section thigh section reclining direction. Rotating the switch arm in the protrusion direction aboutthe pivot point 93 direction would cause rotation of the represented section to recline pivotably in an upward direction by causing the linear actuator, which moves that section, to extend or retract until switch arm is released or section limit switchfor maximum recline was reached by the section. Rotating the switch arm in the protrusion direction about the pivot point 93 would cause rotation of the represented section to recline pivotably in an upward direction by causing the linear actuator,which moves that section, to extend or retract until switch arm is released or section limit switch for maximum recline was reached by the section. The button 95 on the protrusion side would correspond to the upward rotation of the section. The calvessection and thigh section are operated by the same switch throughout the rotation about the thigh section from feet elevated past horizontal to coplanar calves section and thigh section (leg section) down. The back arch support button out 97 and backarch support button in 98 would operate the back arch support mechanism 68.

FIG. 28B is a preferred embodiment similar in function to FIG. 28A except that the shape of the reclined bed is further identified by the control housing 94. The back arch support button out 97 and back arch support button in 98 would operatethe back arch support mechanism 68.

Push buttonsare used instead of lever switches. The reclining in the upward rotation would be the upward button 95 near the pillow or head identified surface, or top of bed, and downward button 98 would be the other button beside (or below) it.

FIG. 28E is an alternate embodiment similar in function to FIG. 28D. The calves section/thigh section and back section operate a conventional reclining bed without tilting buttocks section. Push buttons are placed on represented surface andunderside. The reclining in the upward rotation would be the upward button 95 near the pillow or head identified surface, or top of bed, and downward button 96 would be the other button beside (or below) it.

FIG. 28F is an alternate embodiment similar in function to FIG. 28E. The calves section/thigh section and back section operate a conventional reclining bed without tilting buttocks section. Push buttons are placed on represented surface andunderside. The reclining in the upward rotation would be the upward button 95 near the pillow or head identified surface, or top of bed, and downward button 96 would be the other button beside (or below) it. The sensible identification is representedby the human body parts of the head and feet. This body identification may also be with used with the other style of switches such as the lever, or may have the representative body housing hinge at the knee and mid section of the housing in the desireddirection with internal switches to control the appropriate linear actuators.

The book holder base 100 attaches to the desk top 42 or to other places on desks, tables, or lamps etc. The slidearms 101 allow the sliding holder 102 to adjust to the particular book height and allow turning of pages by lifting book slightly while flipping the page.

FIG. 31--shows another position configuration that can be made without adding any components. Other configurations such as this one but with back section horizontal, or just the buttocks section raised, etc., allow person to shift body weightor stretch.

FIG. 32--shows an alternative embodiment using 2 linear actuators for the calve section 4 and thigh section 3. The control of the coplanar calve/thigh section linear actuator 17CT and knee linear actuator 17K could be coordinated by limitswitches on the bed to change the power to the appropriate actuator. The pivot fixture 10 and feet lifting bar include attachment points for the coplanar calve/thigh section linear actuator 17CT and knee linear actuator 17K.

Accordingly, besides the objects and advantages of the reclining bed with desk described in my above patent, several objects and advantages of the present invention are: 1. The reclining bed has the long felt but unrealized disadvantage ofergonomic discomfort in that the body weight of the thighs was slightly shifted towards the buttocks and lower back area due to thighs and feet being raised beyond horizontal and inclined towards, and thus bearing, onto the buttocks and lower back. Atthe same time buttocks and lower back are also carrying the weight of the head, shoulders and back that would be transferred to the lower thighs (just above the knee area of the thighs) when sitting up fully in a chair, especially when leaning forward. This is readily felt when reclining in a typical lawn chair where the buttocks section is horizontal, especially when the calve section is also horizontal and no padding is present, even though the bodyweight of the back, head and shoulders is partiallysupported by the inclined back section. This ergonomic problem is also present with conventional reclining beds but is masked or retarded by the effect of the mattress, and as well as by minimal or partial weight transfer to the lower thigh area whenthe calves section and thigh section are elevated. However with the back reclined and more so with feet elevated simultaneously (fetal position), for long periods, say one hour, in this position results in discomfort in the lower back and tailbone orbuttocks. The fetal position also results in discomfort due to the diaphragm being squeezed by the additional weight not being transferred to the lower thigh area, even though the mattress configuration is similar to the full sit up position, the bodyis generally horizontal not vertical. The applicant's invention recognizes and solves this problem with a bed that will move into a full sit up position resulting in maximum body weight transfer to the lower thigh area and feet, natural loading on spineand diaphragm, and sitting and breathing in a natural position. 2. The invention maintains the horizontal feet elevation capability of the calves section when feet are raised and allows the calves section and thigh section to recline to lock coplanarhorizontally and continue to recline below the horizontal to the floor all in one motion by the same linear actuator. This downward recline is further continued by the tilting upward of the buttocks section while the foot edge stays near the floor. This is even more remarkable that this function of the leg section can be performed by a bed that is a wallhugger, since the entire downwardly recline leg section is moved closer to the wall over and through the bed frame. 3. The adjustable foot restand also the arm rests and back arch support further alleviates body weight from bearing on the lower back and buttocks area and allows body weight to be shifted to varying areas and variety of body positions by the powered actuators resulting in greatercomfort than any existing bed or chair. 4. The invention allows long term sitting without back and buttocks discomfort for entire day use, such as an in an office job situation due to the softer mattress and additional weight distribution area of thecalves and the variation of positions not found on office chairs such as reading while laying horizontal. 5. The invention has custom designed desk, that will provide a work place or recreation place now that long term use is possible. 6. Thebuttocks section tilt eliminates the feeling of forward sliding when back section inclined and thigh section and calves section are horizontal, unlike when buttocks section is horizontal as in conventional reclining beds. The additional feature oftilting the leg section below horizontal with the buttocks section horizontal or tilted, is not possible with existing reclining beds. 7. The invention provides and office sitting area that allows working with the desk at a proper working distance tothe body while reclined and/or feet elevated unlike an office desk and reclining chair where the feet elevation would cause knee, feet and armrests to hit underside of desk as well as the entry and exit of person from the extremely difficult unless thechair could be rolled out first. 8. The invention provides a greater variety working body positions and body weight distribution than any office chair and desk combination. 9. Reduced overall length of the bed for small rooms or bachelor apartmentswhere space is limited and no if no room for couch or desk unlike other wall hugger beds that do not provide addition space at feet end of bed. 10. The invention allows a bed of standard boxspring height of about 12-14 inches to hold standardmattresses of about 10 inches resulting in a bed that is at the sitting height when flat as well as comfortable enter and exit height and safe height, or in the event of falling out of bed. 11. Integrated hoist and desk with armrests combines the costof two separate devices into the one that can be used to assist a person entering or exiting the bed to hoist their body to incremental positions while supporting their body weight on the armrests unlike a crane or gantry. The buttocks sling furthermakes it possible to lift their body from the mattress surface by lowering the buttocks section and using their hands and/or feet to swing to the side of the bed.

The buttocks sling provides a handicapped or injured person a hoisting and swinging device that is self operated. This would allow a bed pan to be inserted under the partially open sling, personal hygiene, or the person could use their arms,feet and legs to swing themselves over to a toilet or bucket of water while being supported by the buttocks sling and arm rest and a back sling across the rear of the two arm rests. This procedure could also be used as to assist entering and exiting ofbed to the stand up position or a wheel chair. The height of a wheel chair is approximately the same as the bed height. The invention's additional positions and ability to shift body weight and buttocks sling to aerate sensitive body areas can preventbed sores. Thus the bed may also be used for hospitalization purposes as well as everyday office work, or any variation or combination of use. 12. The desk serves also as a side table and end table. The side table is generally not used beside a bedsince it blocks the enter and exit area, however with this invention the side table swings out of the way into an end table thereby avoids twisting and reaching to pick up and phone, glass, pen, etc., when used as a desk or side table as compared to anend table. The invention is impact resistant as compared to a mobile table, bed serving tray, side table or end table. 13. The mattress stays secure on boxspring surface but still allows sheets and blankets to be sandwiched between boxspring surfaceand mattress. This surface is essential due the smaller angle between the back section and buttocks section resulting from the higher back elevation relative to other reclining beds and the additional tilt of the buttocks section and the downward forceson the mattress due to the downward slope of the thigh section and calves section. The mattress conforms to the surface of the boxspring without lifting off the surface even with the smaller angles and climbs up the back section surface unlike otherreclining beds where the mattress tends to slide and crush against the foot board. 14. The boxspring's collapsible shroud also acts as a safety shroud and has aesthetic benefit. The same is true for the rear shroud. 15. Sensible controls requires noconfusion of reclining control button location but sensibly identifies the upward and downward pivotal movement of each section of the bed relative to the head of the bed which is identified by the pillow or head simulation protrusion. This is essentialin the dark, or in a drowsy mental state. 16. Provision of a place for a readily available mirror and electric shaver, make up, safe storage for medication, allowing reduced bathroom time and storage space as well as a more comfortable alternativeplace for these activities. 17. Power back arch support further improves and allows change of position and adjustments to be made for long term seating. 18. Standard bed appearance is maintained for marketability and aesthetics. 19. The desk issuperior to a bed tray, resting on thighs, or mobile hospital bed table in the following ways: the desk is easily moved into position even while in bed unlike tables with four swivel castor wheels require moving from a "twisted spine while seated"position the table swivel castored wheels under the be cannot be easily locked by a second person the table cannot be used as a support for entering and exiting the bed, but is actually a hindrance or obstacle preventing enter or exit a bed tray whichmust be either served by a second person or place on a table beside the bed and require twisting and lifting from a "twisted spine seated" position impact resistant as compared to a mobile table, bed serving tray, side table or end table lap topcomputers and books are ergonomically uncomfortable as they require looking down when on the lap, the key board angle is flat in stead of tilted up, and there is no wrist rest area or arm rest the person's thigh may not be shifted for change or varietyof position holding the book to elevate it is tiresome, especially without armrests. wall plug, phone plug are easily accessible where mobile hospital table would be very difficult to maneuver if it has wires attached to it which would dangle from thetable onto the floor alarm clock can be set from the in bed position Operation --Bed positioning--

The switch arm 92 is pivoted at the pivot point 93 to which the rotation on the switch arm 92 would correspond to the movement of the back section or calves section thigh section reclining direction. Rotating the switch arm in the protrusiondirection about the pivot point 93 would cause rotation of the represented section to recline pivotably in an upward direction by causing the linear actuator which moves that section to extend or retract until switch arm is released or section limitswitch for maximum recline was reached by the section. The button 95 on the protrusion side would correspond to the upward rotation of the section. The calves section and thigh section are operated by the same switch throughout the rotation about thethigh section from feet elevated past horizontal to coplanar calves section and thigh section (leg section) down. The back arch support button out 97 and back arch support button in 98 would operate the back arch support mechanism 68. For instance, theswitch arm 92 on the control housing 94 having, protrusion 91 which represents a pillow, is pushed upward to cause the back section linear actuator 17BK to retract, pulling the carriage 5 headward which causes the back bar 24 to elevate the back section1 until the switch arm 92 is released. To lower the back section, the switch arm 92 is pushed downward to cause the back section linear actuator 17BK to expand pushing the carriage 5 footward which causes the back bar 24 to lower the back section 1until the switch arm 92 is released. The back section linear actuator 17BK will automatically stop when either end of it's stroke is reached. This operation is similar for the other linear actuators and their corresponding sections that they move.

The arm rests 44 adjusts for width and tilt and fold out of way when unlocked and rotated horizontally about arm rest folding swivel 77 when the desk is used as side table or end table. The arm rests are locked into the sitting position forentry and exit. To use the desk assembly to enter the bed, for a person requiting maximum support, the person would maneuver their wheel chair to the bedside near the thigh section 3 and calves section 4 pivot edge, facing the feet end of the bed, andthen swing the desk assembly over their wheel chair. The buttocks sling 50 should already be under their buttocks in the wheelchair from their initial entrance, if not then it should be positioned under them. The ends of the buttocks sling 50 and backsling 51 are secured onto the arm rests 44 and the upward force of the height adjustment actuator will lift the person out of the wheel chair. The wheel chair is rolled out from under them and the swivel lock release button 79 pushed and locked "on" sothat both hands and feet may be used to maneuver one's self and desk assembly into center of the mattress with the buttocks section 2 horizontal, and the back section 1 reclined. (The calves section 4 and thigh section 3 may be up but preferably down). The buttocks section 2 is tilted upward by activating the back section lever or push button lifting the person and slackening the buttocks sling 50 ends which are then unsecured and then back sling 51 unsecured. The slings may be left in place forfuture exit of bed, which is the reverse of entering.

To use the desk assembly to enter the bed, for a person requiring partial support, the person would position oneself between the armrests (buttocks sling 50 and back sling 51 may also be secured at this point if needed) and hold the two handgrips 78. The swivel lock release buttons may be configured to release one or more of the swivel locks 47. Both buttons have to be pushed in three depths to filly release all the swivel locks 47 allowing the person to maneuver body and desk assembly tothe bedside near the thigh section and calves section pivot edge, facing away from the bed, with the buttocks section 2 horizontal, and the back section 1 reclined. (The calves section 4 and thigh section 3 may be up but preferably down). The buttockssection 1 is tilted by activating the bask buttocks section lever or push button lifting the person from their feet while the swivel locks are locked to allow stability.

The person then can shift their body weight and buttocks by resting it on their elbows and forearms on the armrest 44, and sliding their buttocks towards the center of the mattress as far as they can by using their legs and feet to push on thefoot rest and the mattress. The swivel locks are then released and the desk assembly positioned further towards the center of the bed and then locked again. This procedure is repeated until they are in position. The buttocks section 2 or the heightadjustment actuator 52 can also be lowered and raised to assist in shifting the body weight to the elbows and forearms. A powered rotary actuator can be added to the swivel locks 47 to assist in the horizontal movements, but is not preferred due to lowresistance of the ball bearings, complexity and cost, but for a person with weak arms and without the use of their lower body, it may be essential and offered as an option.

A sensible shape identification control switch for a reclining bed where the control is permanently mounted or hand held, whether the control housing or switch arm 92 has the protrusion 91 represents the pillow or head of a person to sensiblyidentify the switch for the back section and at the same time identify the orientation of the switch, which in turn identifies the calve/thigh section as not having the head, and in the case of this bed, the buttocks section in the middle. The switcharm 92 is pivoted at the pivot point 93 to which the rotation on the switch arm 92 would correspond to the movement of the back section or calves section/thigh section reclining direction. Rotating the switch arm in the protrusion direction about thepivot point 93 would cause rotation of the represented section to recline pivotably in an upward direction until released or section limit switch for maximum recline was reached by the section. The button 95 on the protrusion side would correspond tothe upward rotation of the section. The calves section and thigh section are operated by the same switch throughout the rotation about the thigh section from feet elevated past horizontal to coplanar calves section and thigh section (leg section) down. The back arch support button out 97 and back arch support button in 98 would operate the back arch support mechanism 68.

The inverted adjustable book holder that attaches to the desk top 42 for reading in the laying horizontal position. The book holder base 100 attaches to the desk top 42 or to other places on desks, tables, or lamps etc. The slide arms 101 allowthe sliding holder 102 to adjust to the particular book height and allow turning of pages by lifting the book slightly.

CONCLUSIONS, RAMIFICATIONS AND SCOPE

Accordingly, the reader will see that the reclining bed with the novel feature that allows a person to sit up and having all the ergonomic benefits of foot and arm rests and back arch support to allow for long periods in the bed. This isfurther enhanced by the ergonomic benefits of power adjusted positions of reclining beds to shift body weight to a variety of positions, such as writing or reading at a desk in a reclined position, which is unobtainable with a chair and desk. Theinvention has made the bed a comfortable place to sit which, in turn, demands the apparatus to facilitate long time periods of work and recreation. The desk is made to fit the new bed now that a desk is needed. The invention has made the desk anintegral part of the bed just as the chair has been part of the desk, the chair however being limited in it's ergonomic functions such as reclining with feet up while still being close enough to the working surface, as well as having blankets or layingflat. The bed is also made into an extension of the bathroom for such things as cosmetic application or electric shaving both requiring vertical seating, mirror, lighting and electrical power and storage compartments, including medicines cabinet. Thisbed offers many benefits to handicapped or seriously injured people and increases the `dependency` boundary so that marginally hospitalized or institutionalized people can now be independent.

Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
